The filling component 1 is provided with a suction component 2 that can accelerate the vacuuming process of the bottle on the basis of avoiding liquid dripping at the filling port of the filling machine. Below the suction component 2, a supporting component 3 is provided that can drive the bottle to be filled to rise and fall in the filling machine.

[0025] In this embodiment: the filling assembly 1 includes a filling machine body 101, a leveling foot 102 is fixedly connected below the filling machine body 101, a liquid inlet pipe 103 is fixedly connected to the liquid inlet end of the filling machine body 101, a liquid outlet pipe 104 is fixedly connected to the liquid outlet end of the filling machine body 101, and a liquid level meter 105 is fixedly installed on the filling machine body 101; the liquid to be filled is accommodated by the filling machine body 101, the height and horizontal degree of the filling machine body 101 are appropriately adjusted by the leveling foot 102, and other liquid injection equipment is connected through the liquid inlet pipe 103 to inject the prepared liquid to be filled into the filling machine body 101, and the liquid to be filled is introduced from the filling machine body 101 to the suction assembly 2 through the liquid outlet pipe 104, and the liquid level of the liquid in the filling machine body 101 is displayed by the liquid level meter 105.

[0026] In this embodiment, the suction component 2 includes a liquid injection part that can quantitatively guide the liquid in the filling component 1, a suction part that can form a negative pressure to suck the residual liquid in the liquid injection part and the air in the bottle to be filled, and a suction part that can quickly extract the air in the suction part. The liquid injection part includes a first valve 201 fixedly connected to the filling component 1, a flow meter 202 is fixedly connected below the first valve 201, and a perfusion pipe 203 is fixedly connected below the flow meter 202. The extraction part includes a second valve 204 fixedly connected to one side of the perfusion pipe 203. , a first connecting pipe 205 is fixedly connected to one side of the second valve 204, a vertical cylinder 206 is fixedly connected to the lower end of the first connecting pipe 205, a cylinder cover 207 is fixedly connected to the lower part of the vertical cylinder 206, a third valve 208 is fixedly installed on the cylinder cover 207, the suction member includes a second connecting pipe 209 fixedly connected to the upper part of the vertical cylinder 206, a pump 210 is fixedly connected to the upper end of the second connecting pipe 209, and the suction assembly 2 also includes a pressure gauge 211 fixedly installed on one side of the vertical cylinder 206; the first valve 201 and the second valve 204 are both electric regulating valves;

[0027] The first valve 201 is used to control the on-off of the liquid from the liquid outlet pipe 104 into the suction component 2 pipeline. The flow meter 202 is used to perform real-time statistics and display of the liquid flow entering the perfusion pipe 203 per unit time. The liquid flowing to the filling machine is led out of the filling machine through the perfusion pipe 203. The second valve 204 is used to control the on-off of the pipeline between the perfusion pipe 203 and the first connecting pipe 205. The second valve 204 and the vertical cylinder 206 are connected through the first connecting pipe 205. After the pump 210 starts working, the air in the container formed by the vertical cylinder 206 and the cylinder cover 207 can be sucked along the second connecting pipe 209. The air pressure in the container is displayed in real time by the pressure gauge 211. The on-off of the air path between the container and the external environment is controlled by the third valve 208.

[0028] In this embodiment: the supporting assembly 3 includes a cylinder 301 fixedly installed on both sides of the filling machine body 101, the telescopic end of the cylinder 301 is fixedly connected to a liquid collecting box 302, the upper part of the liquid collecting box 302 is movably connected to a drain plate 303, and the drain plate 303 is fixedly connected to a drain frame 304; the drain plate 303 and the drain frame 304 are integrally formed with a through groove, the drain frame 304 is a bowl-shaped structure with a central depression, and the axis of the filling tube 203 coincides with the drain frame 304; the liquid collecting box 302 that can accommodate a certain amount of liquid is driven by the cylinder 301 to rise and fall relative to the filling machine body 101, and a small amount of liquid dripping during filling can fall into the liquid collecting box 302 through the drain plate 303 and the drain frame 304, and the bottle to be filled is placed through the drain frame 304 so that the bottle mouth can be quickly aligned with the filling tube 203.

[0029] Working principle: When the liquid vacuum filling machine is installed and used for the production of feed additives, the liquid inlet pipe 103 is connected to the external liquid injection equipment to batch inject the liquid feed additive to be injected into the filling machine body 101 for vacuum filling, and the liquid level meter 105, the first valve 201, the flow meter 202, the second valve 204, the pump 210, the pressure gauge 211, the cylinder 301 and other components are electrically connected to the control device to control the operation of each component in the filling machine and display its operating status;

[0030] Specifically, during filling, the first valve 201 and the second valve 204 should be in the closed state in advance, and the pump 210 should be used to draw the inside of the container formed by the vertical cylinder 206 and the cylinder cover 207 into a vacuum state. This process can be displayed in real time by the pressure gauge 211. When the bottle to be filled is placed centrally on the bitumen frame 304, and the cylinder 301 drives it to move upward along with the liquid collecting box 302 and other parts, so that the filling tube 203 is tightly inserted into the bottle mouth, the second valve 204 can be opened to allow the vacuum state of the extraction part to quickly suck the air in the bottle. When the pressure gauge 211 shows the vacuum state again, the pump 210 can be stopped, the second valve 204 can be closed, and the first valve 201 can be opened to make the filling machine body The liquid in 101 can be drawn into the bottle through the liquid outlet pipe 104, the first valve 201, the flow meter 202, and the filling pipe 203. When the flow meter 202 shows the filling requirement, the first valve 201 can be closed and the cylinder 301 can be reset to the liquid collecting box 302, so that the filled bottle is separated from the filling pipe 203 and falls to the original height, so that the staff can smoothly replace the bottle. During this process, the second valve 204 can be opened and the pump 210 can be operated, so that the vertical cylinder 206 can suck the residual liquid in the filling pipe 203 through the first connecting pipe 205 and the second valve 204. After the new bottle is placed, the second valve 204 can be closed and the pump 210 can be operated to repeat the above filling process;

[0031] During a filling interval, the third valve 208 can be opened after the second valve 204 is opened, so as to discharge the liquid accumulated in the container formed by the vertical cylinder 206 and the cylinder cover 207.

[0032] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
